When somebody calls your TwiML number, this markup will tell TwiML to dial +155555555 and if someone answers the call, it will record the call to 155555555. This may be illegal in your country if neither party has consent of the recorded call.

Dial with the record=”record-from-answer” can also be set to record-from-ringing-dual if you want it to record before 155555555 even answers, or even if they don’t answer.
